1. , the present invention relates to the remote sensing estimation method of yield loss of crop multimetadata crop rotation cycle, relate to agricultural and association area, the object of estimation in big geographic area all owing to lack the crop yield that normal crop rotation causes and lose, the decipher result who spatially changes with the crops in the remote sensing image is as the data of estimation polynary several periods of crop-rotation of crops, estimate actual polynary several periods of crop-rotation of crops by the formula of setting up, actual polynary several periods of crop-rotation with crops compared with minimum necessary polynary several periods of crop-rotation again, estimate because the inappropriate crop yield loss that causes of polynary several periods of crop-rotation of crops, this method has efficiently, simply, characteristics such as be widely used, can be widely used in the field such as is estimated in zone or the whole world production loss relevant with crop rotation, the invention further relates to the technology of this method of realization.
